These risks include, without limitation (1) that we may not be able to execute our strategy to be a leading IT services and communications provider, which could adversely affect our results of operations and cash flows; (2) that we may not be able to grow revenues from our growth products and services to offset declining revenues from our traditional products and services, which could adversely affect our results of operations and cash flows; (3) that our failure to achieve operating efficiencies will adversely affect our results of operations; (4) that as a result of our continuing review of our business, we may have to undertake further restructuring plans that would require additional charges, including incurring facility exit and restructuring charges; (5) that we may be unsuccessful integrating acquisitions into our business, which could result in operating difficulties, losses and other adverse consequences; (6) that if we are unable to adapt to changes in technology and customer demands, we may not remain competitive, and our revenues and operating results could suffer;

(9) that we face significant competition in the communications and IT services industry that could reduce our profitability; (10) that failure to retain existing customers could adversely affect our results of operations and cash flows; (11) that decisions by legislative or regulatory authorities, including the Federal Communications Commission relieving incumbent carriers of certain regulatory requirements, and possible further deregulation in the future, may restrict our ability to provide services and may increase the costs we incur to provide these services; (12) that if we are unable to interconnect with AT&T, Verizon and other incumbent carriers on acceptable terms, our ability to offer competitively priced local telephone services will be adversely affected; (13) that our operating performance will suffer if we are not offered competitive rates for the access services we need to provide our long distance services; (14) that we may experience reductions in switched access and reciprocal compensation revenue;

(23) that potential regulation of Internet service providers could adversely affect our operations; (24) that cyber security breaches could harm our business; (25) that privacy concerns relating to our business could damage our reputation and deter current and potential users from using our services; (26) that interruption or failure of our network, information systems or other technologies could impair our ability to provide our services, which could damage our reputation and harm our operating results; (27) that our business depends on effective business support systems and processes; (28) that if we, or other industry participants, are unable to successfully defend against disputes or legal actions, we could face substantial liabilities or suffer harm to our financial and operational prospects; (29) that we may be accused of infringing upon the intellectual property rights of third parties, which is costly to defend and could limit our ability to use certain technologies in the future; (30) that we may not be able to protect our intellectual property; (31) that we may be unable to hire and retain sufficient qualified personnel, and the loss of any of our key executive officers could adversely affect us; (32) that government regulations could adversely affect our business or force us to change our business practices; (33) that our business may suffer if third parties are unable to provide services or terminate their relationships with us; (34) that we may be required to recognize impairment charges on our goodwill and intangible assets, which would adversely affect our results of operations and financial position;

(40) that our stock price may be volatile; (41) that provisions of our certificate of incorporation, bylaws and other elements of our capital structure could limit our share price and delay a change of control of the company; and (42) that our bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders' flexibility in obtaining a judicial forum for disputes with us or our directors, officers or employees.

Accounts receivable, net of allowance of $7,872 and $8,615 as of December 31, 2012

During the first quarter of 2013, the Company recognized a $256.7 million non-cash impairment charge to goodwill related to its Business Services reporting unit, of which $255.6 million is included in continuing operations and $1.1 million is reflected in discontinued operations. The impairment was based on an analysis of a number of factors after a decline in the Company's market capitalization following the announcement of its fourth quarter 2012 earnings and 2013 financial guidance. The primary factor contributing to the impairment was a change in the discount rate and market multiples as a result of the change in these market conditions, both key assumptions used in the determination of fair value.

Restructuring, acquisition and integration-related costs consist of costs related to restructuring, acquisition and integration-related activities. Such costs include: 1) integration-related costs, such as system conversion, rebranding costs and integration-related consulting and employee costs; 2) severance, retention and other employee termination costs associated with acquisition and integration activities and with certain voluntary employee separations; 3) transaction-related costs, which are direct costs incurred to effect a business combination, such as advisory, legal, accounting, valuation and other professional fees; and 4) facility-related costs, such as lease termination and asset impairments. The Company expects to incur restructuring, acquisition and integration-related costs of approximately $7 million in the first quarter of 2014 and $17 million for the full year 2014. The Company expects these costs to generally decline throughout the year.

3.

The income tax provision for the three and twelve months ended December 31, 2013, includes a $266.3 million non-cash charge to record a valuation allowance against the Company's deferred tax assets. During the fourth quarter of 2013, the Company determined it will not be able to fully realize its deferred tax assets in the future.

4.

The operating results of the Company's telecom systems business acquired as part of ITC^DeltaCom have been separately presented as discontinued operations for all periods presented. On August 2, 2013, the Company sold its ITC^DeltaCom telecom systems business. The Company has no significant continuing involvement in the operations or significant continuing direct cash flows. The telecom systems results of operations were previously included in the Company's Business Services segment.

5.

Adjusted EBITDA is defined as net income (loss) before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation expense, impairment of goodwill and intangible assets, restructuring, acquisition and integration-related costs, and loss from discontinued operations, net of tax. Unlevered Free Cash Flow is defined as net income (loss) before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation expense, impairment of goodwill and intangible assets, restructuring, acquisition and integration-related costs, and loss from discontinued operations, net of tax, less cash used for purchases of property and equipment. Net Loss Excluding Valuation Allowance is defined as net loss excluding the non-cash charge to record a valuation allowance against deferred tax assets.

Adjusted EBITDA, Unlevered Free Cash Flow and Net Loss Excluding Valuation Allowance are non-GAAP measures and are not determined in accordance with U.S. generally accepted accounting principles. These non-GAAP financial measures are commonly used in the industry and are presented because management believes they provide relevant and useful information to investors. Management uses these non-GAAP financial measures to evaluate the performance of its business and determine bonuses. Management believes that excluding the effects of certain non-cash and non-operating items enables investors to better understand and analyze the current period's results and provides a better measure of comparability. There are limitations to using these non-GAAP financial measures. Adjusted EBITDA, Unlevered Free Cash Flow and Net Loss Excluding Valuation Allowance are not indicative of cash provided or used by operating activities and may differ from comparable information provided by other companies. Adjusted EBITDA, Unlevered Free Cash Flow and Net Loss Excluding Valuation Allowance should not be considered in isolation, as an alternative to, or more meaningful than measures of financial performance determined in accordance with U.S. GAAP.

6.

The Company reports segment information along the same lines that its chief executive officer reviews its operating results in assessing performance and allocating resources. The Company operates two reportable segments, Business Services and Consumer Services. The Company's Business Services segment provides a broad range of data, voice and IT services to retail and wholesale business customers. The Company's Consumer Services segment provides nationwide Internet access and related value-added services to residential customers.

The Company presents its Business Services revenue in the following three categories: (1) retail services, which includes data, voice and IT services provided to business customers; (2) wholesale services, which includes the sale of transmission capacity to other telecommunications carriers and businesses; and (3) other services, which primarily consists of web hosting. The Company's IT services, which are included within its retail services, include data centers, virtualization, security, applications, premises-based solutions, managed solutions and support services. The Company presents its Consumer Services revenue in the following two categories: (1) access services, which includes narrowband and broadband Internet access services; and (2) value-added services, which includes revenues from ancillary services sold as add-on features to EarthLink's Internet access services, such as security products, premium email only, home networking and email storage; search revenues; and advertising revenues.

EarthLink evaluates performance of its operating segments based on segment income from operations. Segment income from operations includes revenues from external customers, related cost of revenues and operating expenses directly attributable to the segment, which include expenses over which segment managers have direct discretionary control, such as advertising and marketing programs, customer support expenses, site operations expenses, product development expenses, certain technology and facilities expenses, billing operation and provisions for doubtful accounts. Segment income from operations excludes other income and expense items and certain expenses that segment managers do not have discretionary control over. Costs excluded from segment income from operations include various corporate expenses (consisting of certain costs such as corporate management, human resources, finance and legal), depreciation and amortization, stock-based compensation expense, impairment of goodwill and intangible assets and restructuring, acquisition and integration-related costs, as they are not evaluated in the measurement of segment performance.

Average subscribers for the three month periods is calculated by averaging the ending monthly subscribers or accounts for the four months preceding and including the end of the quarterly period.

10.

ARPU represents the average monthly revenue per user (subscriber). ARPU is computed by dividing average monthly revenue for the period by the average number of subscribers for the period. Average monthly revenue used to calculate ARPU includes recurring service revenue as well as nonrecurring revenues associated with equipment and other one-time charges associated with initiating or discontinuing services.

11.

Churn rate is used to measure the rate at which subscribers discontinue service on a voluntary or involuntary basis. Churn rate is computed by dividing the average monthly number of subscribers that discontinued service during the period by the average subscribers for the period.
